" TottZZ whom it may 0011mm:

.Be it known that I, EUGENE P. Enwnnns, a citizen of the United States, residing at Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Universal Joints, of which the following a specification.

My invention relates to new and useful improvements in universal joints or conplings for shafts, and the object of my in vention is the reduction of frictional hearing points, simplicity of mechanism and ease of assembling and separation for cleanin Y v In carrying out my invention, I provide a ball and shaft end, a sleeve, and socket members, a pin passing through the ball with the ends projecting as trunnions and rollers thereon. The opposite inner faces of the socket members are made with elliptical channels to receive said rollers, and I preferably employ two circular rows of antifriction balls, one in each socket member,

and means for holding the outermost row in position and for effecting adjustment for wear. Thcball bears on these. rows of balls as bearings, and the rollers. and channels control the revolnble or turning movement of the ball and shaft formed. therewith with reference to the sleeve and socket, all of which is hereinafter more particularly described.

In the drawing, Figure l is an elevation of the universal joint of my invention. Fig. 2 is a longitudinal section on about the broken line to of Fig. 1. Fig. 3 is an elevation of a part of the socket, that is, one

socket member and the sleeve, as if the other parts were removed. F ig. 4 is an elevation ofthe other socket member alone, and Fig. 5 is an elevation of the screw collar employed with the socket member shown in Fig. 4. Figs. '3 and are taken on the dotted line .2 2 of Fig. 2 looking; in opposite directions.

a represents a shaft end and Z) a hall formed therewith and transversely perforated for the pin 0 which passes centrally through the ball and is driven to place; The

respective ends of this pin project from the oppositc'faces of the ball as trunnions and -up0nthese are the rollers (Z 4 These rollers in width each agree substantially with the projection of the pin.

'6 represents a sleeve or equivalent 'c0nstruction adaptfid to receive and engage a shaft inserted therein, and f 7 are socket members, the member 7' being preferably formed integral with the sleeve 6 and provided with a circumferential flange having a recessed face. The socket member 9, as an annulus, is provided, with a circumferential flange g to fit into the recess in the flange f of the socket member f, and screws shown erclusivcly in Fig. 2 are provided to any desired number, and these screws pass through the two flanges f and g to holdthe socket members firmly together.

At opposite points within the socket members f g, I provide elliptical channels or recesses Z m, each socket member having formed therein substantially half of each elliptical channel. These elliptical channels receive the rollers (Z (Z on the ends of the pin 0 and provide for the swinging movement of the shaft 11 and ball 6 with reference to the sleeve 0 and the socket members f g. The inner surface of the socket member is provided with a groove concentric to the opening in the sleeve 0 and in this channel is a row'of anti-friction balls 7'. The socket member 9 is similarly provided with a circular channel concentric with the axis of the universal ioint and in this channel is a row of anti-friction balls 70. The channel for the row of balls 2' is preferably threesidcd as shown in Fig. 2, while the channel for the row of balls Z: is two-sidcd,-the other side being formed in connection with the screw collar h which fits into the open outer end of the socket member 9, screwing therein and coming against the row of balls 70 to complete the ball receiving channel and to take up any looscncss produced by wear. This screw collar h must necessarily be pro-- vidcd with means limiting its rotation which might otherwise be produced by the turn of the row of balls 7;, consequently I have shown a toothed edge to this collar and a dog 2 held by a screw to the surface of the socket member 9. The opening in the collar h, as well as the length of the ellipti cal channels or recesses Z or limit the swing in; or turning movement of the ball I) and shaft (6, but the same is ample to provide for any reasonable angle of divergence between the axisof the shaft 0: and ball 5, and the axis of the sleeve 6 and socket members f g.

The two rows '5 and 7c of anti-friction balls come against the surface of the hall b holding the same and immovablv fixin it:

relation to the socket members, but at the same time permitting 1t to swing or turn wlthln the socket members with the rotation of all the parts, as will be the case in use.

, and at the same time permits the ball 7) and its shaft (4 to swing an amount which will be controlled entirely y the length of these channels, the surfaces of the rollers coming up against the respective ends of the channels.

It goes without saying that the adjustment of the row of balls Z", by the collar 71, for wear also effects the adjustment of the ball I) with reference to the row of balls 7? so that "the parts are maintained in a snug relation to one another without lost motion.

I claim as my invention:

1. A universal joint comprising a shaft end, a hall-lazuli connected thereto, a second shaft end, a semi-spherical socket member connected to the said second shaft end and. having a bearing therein, an annular socket member also having a bearing therein, flanges connected to the said semi-spherical socket member and the said annular socket member, means for securing these flanges together, a pin projecting at diametrically opposite points freer the said ball-head, a roller on each projecting end of the pin, the said socket members being provided With recesses in which the said rollers are received and operated, anti-friction devices in the saidbearings and against which the surface of the said ball-head contacts, and a member surrounding the said shaft and adjustable to position in the said annular socket member for forming one side of the airing for the said anti-friction devices in the said annular socket member.

2. A universal joint comprising a shaft end, a ball head connected thereto, a sleeve,

a semi-spherieal socket member connected to the sleeve and having a recess therein, an Y annular socket member havmg recess therein, a flange connected to the se1ni-- spherical smhet member, a flange connected to the annular socket member, means for securing the flanges together, a pinextending centrally tl'irough the said ball head and projecting beyond the same, a roller on each projecting end of the said pin, the said socket members being provided with elliptical. recesses in which the said rollers are received and operate, a series of anti-friction balls in the recesses in the said socket men'ibers bearing against the faces defining the said recess, therein and also against the surface of the ball head, a collar surrounding the said shaft end and adjustable to position within the said annular socket member, and forming; a bearing for the aIiti-fi.",ti( i1 halls in the recess in the said annular socket member, and means for curing; the said collar in position.

3. A, universal joint comprising a shaft end, a ball head connected thereto, a sleeve,.

a SQlIll-SIJllGljlfiill socket member connected to the sleeve and having a recess therein, an annular socket member also having a recess therein, a llange connected to the sen'iisplieriral socket member, a. flange connected to th annular socket member, mean curing: the flanges together, a pin .ndingig centrally through the said ball head and projecting beyond the same, a relic: on each projecting end oi? the said pin, the seal socket members being provided with elliptical recesses in which the said rollers are received and operated, a series of antiirictien halls in the recesses in the said socket memhers bearing against the faces defining the said recesses therein and also against the surface oi the said ball head, and, a member surromnling the said shaft and adjustable to position in the said-annular socket memher for forming one side of a hearing for the anti-friction balls in the recess in the said annular socket member.
